The swirling type micro-bubble generating system according to the present invention has a container main unit having a conical space or a bottle-like space, a liquid inlet provided in tangential direction on a part of circumferential surface of inner wall of said space, a gas introducing hole provided on the bottom of said space, and a swirling gas-liquid outlet arranged at the top of said space. According to this system, it is possible to readily generate micro-bubbles in industrial scale, and the system is relatively small in size and has simple structure and can be easily manufactured. The system can be used in the applications such as purification of water quality in ponds, lakes, marshes, man-made lakes, rivers, etc., for processing of polluted water using microorganisms, culture of fishes and other aquatic animals, and increase of oxygen and dissolved oxygen in culture solution in hydroponic culture farm and improvement of production yield.
A micro-bubble generating system, comprising a container main unit having a conical space having a bottom portion of a diameter greater than a top portion, a pressure liquid inlet provided in tangential direction to a part of a circumferential surface on an inner wall of said conical space, a gas introducing hole opened on the bottom portion of said conical space for entry of gas into said conical space, and a swirling gas-liquid outlet arranged at the top portion of said conical space, wherein
A method for micro-bubble generation, using a micro-bubble generating system, which comprises a container main unit having a conical space having a bottom portion of a diameter greater than a top portion, a pressure liquid introducing port opened in tangential direction to apart of a circumferential surface on an inner wall of said conical space, a gas introducing hole opened at the bottom portion of said conical space for entry of gas into said conical space, and a swirling gas-liquid discharge outlet opened at the top portion of said conical space, whereby said method comprises a first step of forming a gas vortex flow swirling and flowing while being extended and narrowed toward said top portion of said conical space, and a second step of generating micro-bubbles when the gas vortex flow is forcibly cut off due to the difference of swirling velocity between an upper portion and a lower portion of the gas vortex flow, wherein
